4889-50-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4889-50-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,8 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4889-50:
(6*4)+(5*8)+(4*8)+(3*9)+(2*5)+(1*0)=133
133 % 10 = 3
So 4889-50-3 is a valid CAS Registry Number.
